“…20 and 21 the results for possible combinations of our project target can be seen. For known derivatives of the pitching moment and normal force coefficients ratio of the original missile and assumed required derivatives of the same ratio are determined by changing the wing dimensions and its locations [18][19][20][21][22][23][24][25][26][27]. By varying the shape of the missile models, different values of the derivatives of the normal force and pitching moment coefficients are obtained.…”

Original scientific paper https://doi.org/10.2298/TSCI150515184OThis paper presents modification of the existing guided missile which was done by replacing the existing front part with the new five, while the rear part of the missile with rocket motor and missile thrust vector control system remains the same. The shape of all improved front parts is completely different from the original one. Modification was performed based on required aerodynamic coefficients for the existing guided missile. The preliminary aerodynamic configurations of the improved missile front parts were designed based on theoretical and computational fluid dynamics simulations. All aerodynamic configurations were tested in the T-35 wind tunnel at the Military Technical Institute in order to determine the final geometry of the new front parts. The 3-D Reynolds averaged Navier-Stokes numerical simulations were carried out to predict the aerodynamic loads of the missile based on the finite volume method. Experimental results of the axial force, normal force, and pitching moment coefficients are presented. The computational results of the aerodynamic loads of a guided missile model are also given, and agreed well with.

“…The simulation model is based on the factor of the speed of the airflow and the data are valid for the area in which the device is used. The primary real model on which laboratory testing was carried out has been questioned by several factors [6][7]. Due to the amount of work in this study, it was not possible to include all the iterations that have been tested on a real model, and the simulation is performed only for some specific parameters.…”

“…The boundary layer over a flat plate can also be considered as inner and outer layers with their own specific scaling and scaling between Wind Tunnels [7,8]. In fact, the boundary layer velocity profile of turbulent flow over a flat plate (zero pressure gradients) has a larger velocity gradient at the wall since it is much fuller than the one in the laminar flow.…”
